Mariah Carey is officially single! Mariah was trying for more than a year to get Nick off the dime and sign divorce papers. She’s wanted to get married to billionaire James Packer for months, but the divorce made it a non-starter. We’ve just learned at the end of the summer, right before Mariah and James boarded a yacht in Greece, Nick signed the docs and the divorce was a done deal. Nick and Mariah agreed on joint custody of their 5-year-old twins. Neither gets child support.
